To 'whom it' may concern:

Be `it known that lf, Hessen L. Hersenen e citizen of the UnitedStates.J residing; et Springlield, in the county ot @lark end State ofhio, have invented certain new and useful Improvements in Locked Nuts,et which the following is a specification.

This invention relates to improvements in looked nuts, and the object ofthe invention is to provide a nut equipped with means of a simple natureby which the not may readily and effectively looked in position on ashziit or other device in connection with which it is designed to beused.

ln the aocoaiponying drawings -l'igure is'a longitudinal section of :iball bearing' on a shait showing my improved out applied thereto. Fig.is o. side elevation oit the nut. Fie'. 3 is a section ou the. line 3-3of Fig. il.

lnY the said drawings, l represents a, nut lniviiiiiV o screuethreadedinterior and an'e terioifof conventional torno. The b lf of the nut isprovided with two diainetrioally opposite recesses, 2 and 3, extendingiongitudinally through the nut, which may be formed by coring or .in anyother suitable Way. Extending trom the end of each recess to theinterior of the not ere slits Ll and tfwhich may be formed by sawingthrough .tliiit portion of the metal; each of the slits being preferablyat that end ot the corresponding; recess opposite the direction in whichthe nut turns in tighteninf. Thread ed into those portions ot the notbetween the exterior thereon and the recesses are setserews and 7. theinner ends of the setserea's bearing upon those portions of the nut lnend i which are separated from the mein body of the nut by the recessesand slits.

in Fig. l, l have shown the device applied to a shaft 9 for'the purposeot holding,- a ball screws. ln practice it has been found that thisarrangement furnishes a. simpleIJ economical. and effective Way otsecurely loot:- ing the not in position.

lilaving thu-s described' my intention, li olaiuu l. in a locked nut, obody portion having' a recess' and also haring i slit extending: fromone end of said recess to the interioi` of said body, and a set-sorew inthat portion ol the body between the recess and tho extorior thereoiIarranged to Contact that portion ot said body between said and theinterior thereof.

2. ln o locked nut, a, main body portion boring two diainetiicallyopposite longitudinally extending recesses and also boring' slitsextending1 troni the ends of the respective recesses to the interior oisaid body, a set-screw threaded into those portions oit the body betweensaid recesses and the exterior thereof and ai 'ringed to bear againstthose portions of the body between said recesses and the interiorthereof.

3. ln a locked nut, the combination with. e. screwthreaded member, ot' anut body hat* ing a, screwthreaxied interior threaded on seid member andan exterior of conventional torno, said body also having; alongitudinallyextending 'recess and aslit extending from one end of saidrecess to the serejwthreaded interior thereof, and a` set-screw threadedinto that part ot said body between said recess and the exterior thereofand au ranged to bear against that portion ot said body between seidrecess and the interior thereof.

4t. in a locked not, the combination 'with a screwthreaded member, ot oout body haya serewthreafded interior threaded upon said nieniber andanexterior ol Conventional forni, seid main body having di; of oppositelongitudineily.extendingi reces e@ and a slit extenu'liniggl from theend oit e: y.Li recess to the srrowthreoded interior thereot.l andset-screws threaded into those portions oit said main body between said'recesses and 'the exterior thereof and bearing" against those portionsof said main body :lying between said recesses and the interior thereot.ntestimony whereof, have hereunto my hand this 29th day of @ctoberli915.
